The Split-Luciferase Complementation Assay to Detect and Quantify Protein-Protein Interactions in Planta.

Abstract

Protein-protein interactions play a critical role in plant viral infection and defense responses against pathogens. This protocol provides a detailed and reliable methodology for investigating protein-protein interactions using a luciferase-based complementation assay that includes easy luminescence-based normalization within a single plate. The protocol includes step-by-step procedures, reagent lists, and considerations for data interpretation, ensuring robust and reproducible results. By following this protocol, researchers can advance on understanding of the crucial role of protein-protein interactions in plant viral infection and defense responses to other pathogen attacks.
